Point slope form
(y-y1)= m(x-x1)
Point
(X1= -6, y1=4)
Slope
m= 3-4/1+6= -1/7
Answer is
y-4= -1/7(x+6)
Slope intercept
y= mx +b
y-4= (-x/7) -6/7
y= -x/7 -6/7+4
Answer is
y= -x/7 +22/7
Answer:
= 6n - 2
Step-by-step explanation:
Because you can use the formula = a1 + d (n - 1) to identify the arithmetic sequence :)
<h3>Answer: Choice B) 8.57</h3>
==================================================
Explanation:
The triangles are similar through the AA (angle angle) similarity rule. Note how the angle markers correspond and match up. Example: angle C and angle F both have triple angle markers to indicate these angles are congruent.
The corresponding sides pair up to form equal fractions. AB and DE form AB/DE which is equal to AC/DF, as these two sides correspond as well.
Therefore: AB/DE = AC/DF
Let's plug in the given values and isolate x
AB/DE = AC/DF
11/7 = (15+x)/15 ...... substitution
11*15 = 7*(15+x) ....... cross multiply
11*15 = 7*15+7*x ...... distribute
165 = 105+7x
165-105 = 105+7x-105 ..... subtract 105 from both sides
60 = 7x
7x = 60
7x/7 = 60/7 ............ divide both sides by 7
x = 8.57142857142858
x = 8.57 ..... rounding to the nearest hundredth
Answer:
the first one is 24

Answer:
13. part a
What Lenora did wrong is that when you multiply 2 terms, the exponents are added not multiplied. It would be 10x^4y^6
13. part b
2xy^4
when the terms are divided, the exponents are subtracted
